Question The Room from Hell for Speaker Placement

Due to the insane design of our primary living/lounging/tv watching room I am forced to used two (2) speakers for the left surround position. If the supplemental speaker is not used the left surround output is not heard by all. There is not "if's and's or but's" about this situation. The problem is so bad I've given sincere consideration to dumping the 6.1 setup for a vitural surround system.

We're running a Harman Kardon AVR 525 with Infinity Alpha speakers. Here's the speaker setup = A50's in front, A37C in center, A20's as surrounds (an Infinity A10 is the supplemental second left surround), an A10 as the sole surround back and a Infinity 1200 sub.

The room measures approximately 12'x17'. For clarity let's name the rooms walls as follows - left end, right end, top and bottom.

Wall Notes - The left end wall is not an actual wall. Rather it's an open archway between the living room and the dining room. The bottom wall is also a wall in name only as it has no real run of conventional wall surface. The left end of the bottom wall opens into the stairs, the middle area of the bottom wall is actually a nook beside the stairwell and provides space for my wife's chair while the right end of the bottom wall is a open through-way to the front door and the library. There is not remarkable about the top wall or right end wall.

Due to the rooms shape the surround and surround back cable runs average 45' to 50' each while the actual speakers are only about 12' from the AVR.

Here's my question. What is the safest, most efficient and best performance method to intergrate this supplemental left surround into the speaker system?

Thanks in advance.

Basically whatever works for you... You basically have too many open spaces for the sound to bounce into. You could investigate the possiblility of closing up the room with some folding dividers, or heavy curtains.

Our old home theater had a huge archway into the living room, and another smaller archway into the kitchen. We closed off the kitchen with a heavy curtain that was tastefully matched to the decor.

The larger archway was closed off with a nice set of folding doors. Mind you there was still an open space at the top, but some creative curtains here would have filled the gap.

The supplemental speaker is really going to throw off the dynamics for you. However, this is safe as long as you match the impedance of your load to your amp. How many ohms per channel is your amp rated for?

Have you tried setting up the room kitty corner? I know it is not ideal, but it sounds like it would be better than what you have right now.

I have a large opening on my left wall to the dining room also and a door to the foyer on the right side. Part of what makes this work is that I have Klipsch surrounds that are 180 degree speakers. This setup sounds great considering the layout.

Good luck!
